Title: Eddy current flaw detection for weld-seamed tube
Inventor: TONO KEIGO
IPC: G01N27/90
Filed: 1984-08-15
Abstract: PURPOSE:To facilitate the detection of a fine defect at a weld part of a weld- seamed tube, by making a part of a coil bobbin of a through type eddy current flaw detection element thinner than other parts thereof to bring the weld part near the thinner part. CONSTITUTION:An eddy current flaw detection element 13 which comprises a coil bobbin 11 having a cylindrical bobbin with a thinner part and a coil 12 is used to perform an eddy current flaw detection on a welded cylindrical tube 2 having a weld part 1. The coil 12 is connected to an eddy current flaw detector body with a wire 14 and a welded cylindrical tube 2 is passed through the eddy current flaw detection element 13 in such a manner that a length-wise weld part 1 is brought near the thinner part of the bobbin 11. An eddy current I generated in the welded cylindrical tube 2 flows unevenly to concentrate most on the weld part 1. Any fine weld defect can affect the flow of the eddy current generated so greatly as to obtain a large detection signal. Thus, the detection signal other than the weld-seamed defect will be suppressed drastically to improve the S/N ratio.

Abstract: PURPOSE: To deliver cartridges reliably to each position of a firing weapon by curving a cartridge infeed channel arcuately with the center of curvature being set in an attack angle axis and telescoping the channel depending on each position of the firing weapon in an attack angle plane when a carrying chain varies the attack angle of the firing weapon. CONSTITUTION: Cartridges 16 are delivered from a cartridge magazine 14 to a bucket chain 17 thence to a firing weapon 11. An infeed channel 20 is shortened or lengthened during continuous firing depending on the attack angle of the weapon 11. When the weapon 11 inclines downward by -10 deg., the infeed channel 20 is retracted completely and when the weapon 11 inclines upward by +45 deg., the infeed channel 20 is pushed in completely. The distance (a) between individual buckets 21 in the bucket chain 17 is thereby decreased to distance (b). Three groups A, B and C of guide rail 25-40 are contracted completely at the time of maximum attack angle and thereby they are withdrawn completely.
